Unfortunately, once an application has been submitted it can not be changed. It is therefore recommended to take your time and fully review all of your application information on the "Review" page of the application process.
The Review page will always occur prior to the final Submit page. On the Review page, you will be shown every area of the application process you have completed so far, including the specific questions you were asked and the responses you provided. If you review a section (like Hard Skills, Soft Skills, Virtual Interview, Personal Information, etc.) and find information which needs to be changed, click on the "Edit" button for that section. The Edit button will always appear in colored text to the right of the section header.
Once you click the Edit button, you will be taken back to that section of the application process to make your necessary changes. After making your changes, click "Save and Continue." You will not need to go through the entire application process again, but rather you will be taken back to where you left off on the Review page. This way, you can go from start to finish and double check all of your information prior to final submission.
Unless the company to which you applied has provided additional public contact information, you will not be able to reach out to notify them of incorrect information included with your application. It is therefore very important to make sure the primary telephone number and primary e-mail address included with your application is correct.
